During IFA 2026, Belkin announced a new lineup of magnetic Qi2 battery banks using a new solid-state technology. The two UltraCharge Pro models can charge devices at up to 15W wirelessly, but they have more tricks in the sleeve.
It’s a little difficult to find good magnetic batteries that offer a reliable experience. The Qi2 standard isn’t exactly new, but plenty of batteries that snap to the back of your phone might not be capable of reaching 15W.
Belkin announced two new magnetic Qi2 batteries. They follow a common split into a 5,000mAh and a 10,000mAh power bank. Belkin says both UltraCharge Pro batteries are built on what it’s calling “BoostSolid” technology using internal gel layers for better performance, which it’s advertising lasts up to three times longer than other power banks.
That estimate comes from its ability to retain 80% capacity after 1,000 charge cycles. That’s a five-year lifespan on a full charge cycle every two days.
